Answer:

c= (f-d)/ab

Step-by-step explanation:

abc+d = f
Subtract f from both sides so abc= f-d
Divide by ab from both sides so c = (f-d)/ab

Look at the graph below. what is the slope of the line ?

kykrilka [37]

Answer:

The slope is $-\frac{1}{5}$ .

Step-by-step explanation:

Choose 2 points on the graph.

(7,3) and (2,2)

Use slope formula: $\frac{y2-y1}{x2-x1}$

$\frac{2-3}{2-7}$ = $\frac{-1}{-5}$

The slope is $-\frac{1}{5}$ .

Write an equation of the line that passes through (2,7) and is parallel to the line shown ( please help !! )

Anna007 [38]

Answer:

$y=2x+3$

Step-by-step explanation:

We will first need to determine the slope of the line shown.

We know that it passes through the two points (-2, -2) and (1, 4).

Thus, we can use the slope formula to find the slope between the two points:

$\displaystyle m=\frac{y_2-y_1}{x_2-x_1}$

Let (-2, -2) be (x₁, y₁) and let (1, 4) be (x₂, y₂). Substitute:

$\displaystyle m=\frac{4-(-2)}{1-(-2)}=\frac{6}{3}=2$

Hence, the slope of the original line was 2.

Since we want the new line to be parallel, the slope of the new line must also be 2.

We know that the slope is 2 and it passes through the point (2, 7).

So, we can use the point-slope form:

$y-y_1=m(x-x_1)$

We will substitute 2 for m. We will also let (2, 7) be (x₁, y₁). Substitute:

$y-7=2(x-2)$

Solve for y. Distribute the right:

$y-7=2x-4$

Add 7 to both sides. Hence, our equation is:

$y=2x+3$

Determine the arc length in radians.... need major help please!!!

In-s [12.5K]

If you're supposed to find the measure of the arc:

The minor arc CD has the same measure as the central angle it subtends. In this case, arc CD has measure 50º. In radians, that's

50º * (π/180 rad/º) = 5π/18 rad

If you instead meant to ask about finding the length of the arc CD, recall that arc lengths and their subtended central angles occur in a fixed ratio equal to the ratio of the circle's total circumference to 2π rad. In other words, if L is the length of the minor arc CD, then

L /(5π/18 rad) = 2π (7 cm) / (2π rad)

==> L = 35π/18 cm

(Notice that arc measure is given radians, while arc length is given in cm, which is why I offer two different answers here.)
